DETAQHABLE ADJUSTABLE STOVE-GRATE.

Specification of Letters Patent.

Patented June 12, 1906.

Application filed September 12, 1904. Serial No. 224.083.

To all whom it may concern.-

Be it known that I, IRVING G. CHATFIELD, a citizen of the United States,and a resident of lVaterbury, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inDetachable Adjustable Stove-Grates, of which the following is aspecification.

My invention relates to new and useful im provements in detachablecombined stovegrates and fire-pots adaptedfor burning charcoal inordinary coolcstoves and is designed to be used above and in lieu of theordinary coal-grates found in stoves of this class.

It is the object of my invention to provide a shallow stove-grate andfire-pot which may be set in the fire-box of an ordinary cookstove andused for burning charcoal without disturbing or rearranging any of theparts of the stove, excepting to remove the lids, which may again beused for covering my novel grate.

It is the special object of this invention to provide a grate andfire-pot for the above purpose which may be made up of several partssecured together in an adjustable manner to make it fit stove-openingsof different sizes, thus avoiding the necessity of making special gratesfor the numerous sizes of stoves. The grate is not only adjustablelengthwise, but sidewise, and can thus be employed to accommodate almostany width or length of fire-box opening found in the ordinarycooking-stove.

It is further an object of this invention to construct the parts in sucha way that the same may be formed of cast metal and without thenecessity of any great amount of finishing, and, finally, to provideadjustments which will be simple in character and easily set.

With the above and other minor objects in view my invention resides andconsists in the novel construction and combination of parts shown up onthe accompanying sheet of drawings, forming a part of thisspecification, upon which similar characters of reference denote like orcorresponding parts throughout the several figures, and of which- Figure1 shows a side elevation of my improved adjustable charcoal-grate andfire-pot complete. Fig. 2 is a detail perspective view of the plate orframe member of my device, and Fig. 3 shows similar detached perspectiveviews of the four bottom sections of the invention.

Referring to the drawings, it will be noted that my device consists ofsubstantially five parts, with the exception of several bolts and nutsthat are employed to secure the parts toether. Each of these sections ispreferably ormed of cast metal, being designed in a manner to permit oftheir free withdrawal from the sand of the mold in a way to formsubstantially a complete article that will require little or no fittingand the addition of but small parts in its assemblage.

Referrin in detail to the characters of reference mar ed upon thedrawings, A represents the top or frame member. B,C,D, and E indicatethe several bottom sections forming the grate, which, as shown in Fig.1, are not only adjustably secured to the frame A, but are alsoadjustably secured together.

The frame A is provided with earsff, one on each end, by means of whichthe complete device may be handled. g g indicate recesses in the topedge of the sides of the frame to receive the T or bridge plate of thestovecovers. h represents lugs on each side of the lower portion of theframe, which are provided with horizontal slots a, through which bolts jare passed in the attachment of the sections of the grate to the frame.These several sections of the grate and fire-pot are also provided withlugs (designated as 76) and containing transverse slots Z, through whichthe be fore-mentioned bolts j are passed in the attachment of thesections to the frame. I

It will be noted that the slots in the lugs of the sections are arrangedat a right angle to the slots in the lugs of the frame, thus afiordingboth a longitudinal and transverse adjustment of said sections withrespect to the frame, permitting an adjustment which will readilyincrease or diminish the size of the fire-pot both as to length andwidth. The bottom of the fire-pot is provided with transverse andlongitudinal slots forming transverse and longitudinal grate-bars m.

The sections B and C of the fire-pot are provided with offsets n ontheir outer ends to receive the straight transverse ends 0 of thesections D and E, respectively. The outer ends of said sections areprovided with transverse slots 19 to receive the bolts g, whichadjustably secure such end portions of said sections to ether. The sidesof the sections are provi ed with a similar adjustable connection, anoffset 0 being formed on each of the sections B and D to receive theends 8 of the sections C and E. These parts are also provided withregistering slots t, through which the bolts a pass to secure the sidesof the firepot together, as is clearly shown in Fig. 1. It will also benoted that the under side of-the frame is cut away, as at '0, on eachside and at each end to accommodate the ofiset on sections and in amanner to permit of the desired adjustment of such parts beneath andwith respect to said frame. A further offset to is provided on the innerend of each of the sections 0 and E to receive the straight ends of theabutting sections B and D and to form an extension in the bottom orgrate, as is ob viously necessary when the parts are drawn outward toany of its outer positions.

The sections D and E are further provided with openings at, which formthe draft or flue openings from the grate, it being obvious that theside of the grate containing said openings is the part which in practiceis set toward the back of the stove, thus insuring a proper escape ofthe smoke and gases out into the body of the stove, from whence itpasses off in the usual way.

It will be obvious that the details of con struction of this grate maybe varied without departing from the essence of the invention.Consequently I do not wish to be limited to the exact details shown.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In an adjustable grate and fire-pot, the combination with a frameadapted to fit upon the top of a stove and having lid-openings, and lugson each side, of four grate and firepot sections adjustably attached tosaid lugs of the frame.

2. In an adjustable grate and fire-pot, the combination with a frameadapted to fit on top of a stove and having extended lugs, of grate andfire-pot sections adjustably attached to said lugs and havingoverlapping end and side portions and means for adjustably connectingsaid overlappin portions.

3. In an adjustable grate an fire-pot, of the class described, thecombination with a frame having a lid-opening and side lugs, of grateand fire-pot sections adjustably attachedto the lugs of the frame andalso adjustably connected together.

4:. In an adjustable grate and fire-pot, of the class described, thecombination with a frame adapted to fit on a stove and having lugs onits sides and suitable lid-openings, of grate and fire-pot sectionscomprising end and side portions adjustably connected to the lugs ofsaid frame, and means for adjustably securing said side and end portionsof said sections together.

5. In an adjustable grate and fire-pot of the class described, thecombination with a frame adapted to fit on the top of a stove and havingextended side lugs, of grate and firepot sections secured together andadjustable longitudinally and transversely, and means for attaching saidsections to the lugs of the frame.
